3.6Km/h

Excuse me: how many kilometers per hour do we usually talk about when the speed is 70 yards? How to convert yards into metric units of speed?

Before liberation and in the early days of liberation, many automobile terms were influenced by foreign words, especially by English. For example, the ignition switch was called "switch", the valve was called "valve", and so on. At that time, the speedometer was marked with "Mile", the English was mile, and the Chinese pronunciation was "Mai", So 50 miles per hour is called "50 miles". In the past, the master and his apprentice taught the students how to drive, so the name was passed down. Later, the metric system was changed, and some people mistook the number of kilometers per hour for the number of miles
As for "yard", another unit of length in the English system, it is mispronounced again in the pronunciation of "Mai" (1 yard equals 3 feet, converted into metric system is 0.9144 meters. Football is from England, penalty kick is also called 12 yards, the actual 11 meters, center circle radius is 10 yards, goal width is 8 yards)
One mile equals 1.609344 km, 1760 yards. All speedometers in the United States mark miles
100 km / h is about 62 mph

How many meters is 70 inches?

About 210
